Validator Delegations Example

This example subgraph stores Delegation objects that represent delegations being made in a Cosmos chain. In order to do that, the handler function checks all messages within the transaction and filters them in order to decode and save just the ones that represent a delegation in the chain.

Generating a manifest

The subgraph is compatible with multiple Cosmos networks so before building the subgraph you need to generate a manifest file for the network of your choice. In case of the Cosmos Hub network, run the following command:

$ yarn prepare:cosmoshub

For the list of supported networks, see the scripts in the package.json file.

Querying the subgraph

With the following query you can retrieve all the delegations made to the Figment validator, and the amounts of each of the delegations:

query ValidatorDelegations($validatorAddress: String!) {
  delegations(where: {validatorAddress: $validatorAddress}) {
    validatorAddress,
    delegatorAddress,
    amount {
      amount,
      denom
    }
  }
}

{
    "validatorAddress": "cosmosvaloper1hjct6q7npsspsg3dgvzk3sdf89spmlpfdn6m9d"
}
